similar to: Reconnection problem with a USB device

I just updated an Ubuntu Oneiric to Raring and the VM that works fine on one fails to start a VM with this passthrough: <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x055f'/> <product id='0x040b'/> <address bus='3' device='8'/> </source>

We are using an Intel 82599 chip that allows 4 PFs ( eth0..3) per VM. I am able to manually start VMs using the hostdev definition for the four network connections, but I'd like to start using the pool approach. Ubuntu 12.04 libvirt 1.0.0 Following: http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition I can get a pool working with

I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4. Hi Hongming, I'm hoping you can please help with two issues: 1. The pool works, but I transparent VLAN with the pool does not. I have to manually run "ip" afterwards to get it to work. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

If I'm using the SR-IOV Pool assignment method (from http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition ), how would I check how many virtual functions are already in use? Is there a method other then looping through all the active guests and determining if they're using the SR-IOV interface?

Hi, I try to add 2 VF functions to VM via network. Livirt networks: vnet0: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network> vnet1: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf

Hello, We encountered a problem while testing SRIOV on kubevirt [1]: We are currently using the Device "hostdev" generic options to pass-through the VF to the guest. It is not done through the "interface" (with type hostdev) because that option requires access to the PF which is not available in our case (the VF is moved to the container namespace where libvirt runs, but not

Hi, I've been using libvirt (versions 0.9.11.5, and recently upgraded to 0.10.2), and have been attaching an SR-IOV VF to my VM with the following device configuration: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x07' slot='0x10' function='0x0'/>

Hi folks, Has anyone encountered the following PCI passthrough error? error: internal error Process exited while reading console \ log output: char device redirected to /dev/pts/1 assigned_dev_pci_read: pread failed, ret = 0 errno = 2 It's produced after I've detached the PCI device from the base OS and have tried to start up the guest domain.

There were some changes

I would really appreciate some pointers on what I am doing wrong here. I have a need to run multiple virtual guests which have each their own GPU and some USB controllers passed-through. I am able to run one of the guests like this (assuming vfio stuff has happened elsewhere), but I would prefer to use virsh: kvm -M q35 -m 8192 -cpu host,kvm=off \ -smp 4,sockets=1,cores=4,threads=1 \ -bios

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'

hi laine, thx for the fast answer. i tried VFIO as it seems supported and got at least one step further. starting the guest with one of the DVB cards is possible now, even when the other card is in the hosts pci config (not removed soft or hard). adding the second card/device thru ... > <hostdev mode='subsystem' type='pci' managed='yes'> >

Is the only way to attach a usb device to a vm first specifying the device, <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x3080'/> <product id='0x1234'/> </source> </hostdev> and then booting the vm while the device is attached? Can't I

Hi, We have a VM with several USB devices attached. Everything works well, but sometimes, after a reboot of the host, some usb device get a different bus/device number and that prevent the reboot of the VM : ------- error: Failed to start domain xxx error: internal error: Did not find USB device 04b9:0300 bus:1 device:5 ------- I guess this is because we have multiple usb devices with the same

Let's say I have libvirt [root@vmhost2 ~]# virsh version Compiled against library: libvirt 4.5.0 Using library: libvirt 4.5.0 Using API: QEMU 4.5.0 Running hypervisor: QEMU 2.12.0 [root@vmhost2 ~]# running on centos 8 and then I have this card [root@vmhost2 ~]# virsh nodedev-dumpxml pci_0000_01_00_0 <device> <name>pci_0000_01_00_0</name>

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

I use a virtual machine for a scanner I have for which the vendor never updated their driver. I have accessed it for years using a pass through: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x055f'/> <product id='0x040b'/> </source> </hostdev> I

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is
